<div><span class="Apple-tab-span" style="white-space:pre">	</span>! x &nbsp; 表示用户x发了一条微博；</div>

<div><span class="Apple-tab-span" style="white-space:pre">	</span>- x y 表示用户x和用户y解除了好友关系</div>
<div>当一个用户发微博的时候，所有他的好友（直接关系）都会看到他的消息。</div>
<div>假设最开始所有人之间都不是好友关系，记录也都是合法的（即+ x y时x和y一定不是好友，而- x y时x和y一定是好友）。</div>
<div>问这m条记录发生之后，每个用户分别看到了多少条消息。</div>
<p></p></p><hr/><h3>输入格式</h3><p><div>第1行2个整数n,m。</div>
<div>接下来m行，按时间顺序读入m条记录，每条记录的格式如题目所述，用空格隔开。</div>
<p></p></p><hr/><h3>输出格式</h3><p><div>输出一行n个用空格隔开的数（行末无空格），第i个数表示用户i最后看到了几条消息。</div>
